TEST(1) FSF TEST(1) NAME test - check file types and compare values SYNOPSIS test EXPRESSION test EXPRESSION ] test OPTION DESCRIPTION Exit with the status determined by EXPRESSION. --help display this help and exit --version output version information and exit EXPRESSION is true or false and sets exit status. It is one of: ( EXPRESSION ) EXPRESSION is true ! EXPRESSION EXPRESSION is false EXPRESSION1 -a EXPRESSION2 both EXPRESSION1 and EXPRESSION2 are true EXPRESSION1 -o EXPRESSION2 either EXPRESSION1 or EXPRESSION2 is true [-n] STRING the length of STRING is nonzero -z STRING the length of STRING is zero STRING1 = STRING2 the strings are equal STRING1 != STRING2 the strings are not equal INTEGER1 -eq INTEGER2 INTEGER1 is equal to INTEGER2 INTEGER1 -ge INTEGER2 INTEGER1 is greater than or equal to INTEGER2 INTEGER1 -gt INTEGER2 INTEGER1 is greater than INTEGER2 INTEGER1 -le INTEGER2 INTEGER1 is less than or equal to INTEGER2 GNU sh-utils 2.0 July 2000 1 TEST(1) FSF TEST(1) INTEGER1 -lt INTEGER2 INTEGER1 is less than INTEGER2 INTEGER1 -ne INTEGER2 INTEGER1 is not equal to INTEGER2 FILE1 -ef FILE2 FILE1 and FILE2 have the same device and inode num­ bers FILE1 -nt FILE2 FILE1 is newer (modification date) than FILE2 FILE1 -ot FILE2 FILE1 is older than FILE2 -b FILE FILE exists and is block special -c FILE FILE exists and is character special -d FILE FILE exists and is a directory -e FILE FILE exists -f FILE FILE exists and is a regular file -g FILE FILE exists and is set-group-ID -G FILE FILE exists and is owned by the effective group ID -k FILE FILE exists and has its sticky bit set -L FILE FILE exists and is a symbolic link -O FILE FILE exists and is owned by the effective user ID -p FILE FILE exists and is a named pipe -r FILE FILE exists and is readable -s FILE FILE exists and has a size greater than zero GNU sh-utils 2.0 July 2000 2 TEST(1) FSF TEST(1) -S FILE FILE exists and is a socket -t [FD] file descriptor FD (stdout by default) is opened on a terminal -u FILE FILE exists and its set-user-ID bit is set -w FILE FILE exists and is writable -x FILE FILE exists and is executable Beware that parentheses need to be escaped (e.g., by back­ slashes) for shells. INTEGER may also be -l STRING, which evaluates to the length of STRING. REPORTING BUGS Report bugs to . SEE ALSO The full documentation for test is maintained as a Texinfo manual.
